AIM:To investigate the correlation between lumican(LUM)gene and high myopia in a Southern Chinese population.METHODS:The study comprised of 95 high myopia patients with a spherical equivalent≤-6.5 diopters(D).The control group recruited 95 individuals with a spherical equivalent ranging from-0.5 D to+0.5 D.Direct sequencing was used to detect the single nucleotide polymorphisms(SNPs)of LUM gene in coding region.Genotype distributions were tested for Hardy-Weinberg disequilibrium.Genotypic and allelic frequencies were analyzed through Chi-square test or Fisher’s exact test.RESULTS:We identified 3 SNPs of the LUM gene:LUM c.32(rs577456426),LUM c.507(rs17853500)and LUM c.849(rs181915277).Among the three SNPs,the genotype and allele frequencies of rs17853500 showed a significant difference between patients and control subjects(P〈0.05).However,there were no significant differences in rs181915277and rs577456426 between the two groups(P〉0.05).CONCLUSION:LUM c.507 polymorphism may be a risk factor for the pathogenesis of high myopia in the Southern Chinese population.
